Trane M# SAH007540073A75D3000NTB S# J85F71541 The guard pac never tries to start comp Does anyone know what the resistance is between C S1 S2 and S3 Thanks

around 85 olms, I think if it reads above 120 it wont start, used resisters before on bad sensor to get comp running.

One was bad they had me add a resester to the bad one It fired up and ran good The other comp just stops at diferent times it might run a hour or two or it might run 10 min. I tightend every terminal I could find I will check in the morning if it stays runing Thanks

should be 75 ohms, but 85 is close enough

[dmdrone]

I called trane and they told me to use a 82 ohm resister and it worked thanks

So.............they trip at 265 degrees. Anyone have a temperature/resistance chart?
